Ecological Niches

24.6K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Global Climate Change

24.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Limits to Natural Selection

32.4K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

What is Evolutionary History?

40.4K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

What is Climate?

19.2K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Summary

Birds evolved from warm, wet climates to colder, drier environments, with niche evolution rates increasing over time. This study reveals significant evolutionary changes, especially after the Cretaceous-Palaeogene boundary.

Area of Science:

  • Evolutionary biology
  • Ecology
  • Paleontology

Background:

  • Understanding lineage evolution and niche space adaptation is key to evolutionary biology.
  • Linking empirical niche data with evolutionary models has been challenging, hindering understanding of abiotic and biotic factor influences.

Purpose of the Study:

  • To characterize the niche space evolution of all Aves (birds).
  • To assess how evolutionary rates vary across avian lineages and time, particularly in response to environmental changes like the Cretaceous-Palaeogene (K-Pg) boundary.

Main Methods:

  • Characterized two-dimensional temperature and precipitation niche envelopes of bird species as complex geometries.
  • Applied a model capturing heterogeneous evolutionary rates on time-calibrated phylogenies for all Aves.

Main Results:

  • Extant birds evolved from warm, mesic niches to colder, drier environments.
  • A significant increase in niche disparity was observed following the K-Pg boundary.
  • Overall niche evolution rates have steadily increased, with some lineages showing high rates and novel niche colonization, while others exhibit niche stasis.

Conclusions:

  • Niche evolution is driven by both competition and environmental change, leading to heterogeneous rates.
  • Integrating environmental and phylogenetic data provides ecological and conservation insights into avian evolution.
